AC CHARACTERISTICS
V
Notes
1. The circuit is DC adjusted at V
2. At 18 V < V
3. Output power is measured directly at the output pins of the IC.
4. Frequency response externally fixed.
5. Ripple rejection measured at the output with a source-impedance of 0 , maximum ripple amplitude of 2 V (p-p) and
6. Noise measured in a bandwidth of 20 Hz to 20 kHz.
7. Noise output voltage independent of R
